Mandible – Lateral 30° Cranial (Axiolateral Oblique) Projection
Technique 1: The patient lies supine with the trunk slightly rotated and supported with pads so that the side of the face under examination is in contact with the image receptor. The median sagittal plane is parallel to the receptor and the interpupillary line is perpendicular. The neck may be slightly flexed to separate the mandible from the cervical spine. The image receptor is positioned parallel to the long axis of the mandible with its lower border approximately 2 cm below the mandibular margin.

Technique 2 (Trauma/Horizontal Beam): When the patient cannot be moved, the examination is performed with a horizontal beam. The patient remains supine with the median sagittal plane at right angles to the tabletop, and the image receptor is supported vertically against the side of the face being examined.
Central Ray: Directed 30° cranially (60° to the image receptor) and centered approximately 5 cm inferior to the angle of the mandible on the side nearest the receptor.
Collimation: Include the entire mandible and temporomandibular joint (TMJ), extending to the external auditory meatus (EAM).
Image Criteria: The body and ramus of the mandible should be demonstrated without superimposition, and the entire mandible from the TMJ to the symphysis menti should be included.

A 43-year-old woman presented with a history of anterior neck swelling for 26 years. She had never sought proper medical evaluation and had not undergone any previous imaging studies or biopsy. Over the past few months, she noticed a progressive increase in the size of the neck mass, accompanied by dysphagia and significant weight loss. There was no history of hoarseness of voice, difficulty breathing.No hyper or hypothyroid symptoms .x ray cervical spine was performed what are the findings and diagnosis?

Projection: Superoinferior Tangential (Axial) Projection – Nasal Bones

Patient Positioning
Patient seated erect or prone on the table.
Extend the neck and rest the chin on the image receptor.

Place an angled support under the image receptor so that it is perpendicular to the glabelloalveolarline (GAL). Align the MSP perpendicular to the image receptor and centered to the midline.

Central Ray (CR):-
Direct the CR to the nasion. Angle the CR as required so that it is parallel to the GAL. The CR should skim the glabella and anterior upper frontal region.
Collimate closely to the nasal bones on all sides.
Suspend respiration during exposure.

Camp-coventry method is a specialized radiographic projection of the knee used to demonstrate the intercondylar fossa, along with the articular surfaces of the femoral condyles and tibial spines. It is particularly helpful in evaluating loose bodies, osteochondritis dissecans, and abnormalities or irregularities of the joint surfaces.

Patient Position: The patient lies in a prone position (face down) on the X-ray table.
Knee Flexion: The affected knee is flexed to 40° to 45°.
Central Ray: The X-ray beam is angled caudally (toward the feet) at 40°, centered directly over the popliteal fossa (the back of the knee)

TThe axiolateral oblique mandible view allows for visualisation of the mandibular body, mandibular ramus, condylar process and mentum.
Patient positioning:
he patient is seated upright with the side of interest closest to the detector the head is first placed in a true lateral position interpupillary line (IPL) perpendicular and midsagittal plane (MSP) parallel to the detector then, the neck is sufficiently extended to prevent superimposing the mandibular rami over the cervical spine the vertex (top of the head) is lastly tilted towards the detector to demonstrate the region of the mandible of interest prevent superimposing the opposite side.

A 29-year-old female presented with a gradually progressive swelling over the left thumb associated with pain and restriction of thumb movements. There was no history of trauma, constitutional symptoms, or systemic illness. She had previously received local treatment and later developed skin changes. On examination, a firm swelling measuring approximately 10 × 7 × 4.5 cm was noted over the first metacarpal region, with painful and restricted movements at the metacarpophalangeal and trapeziometacarpal joints.x ray hand was performed what are the findings and diagnosis?
